UNTTE STATES AARON INNIS, OF POUGHKEEPSIE, NEW YORK.

DYE-WOOD CHIPPER.

SPECIFICATION forming part of Letters Patent No. 233,764, dated October 26, 1880.

Application filed April 10, 1880.

To all whom it may concern:

Be it known that I, AARON INNIS, of Poughkcepsie, in the county of Dutchess and State of New York, have invented a new and useful.

The invention consists in the particular means hereinafter described for securing the knives of dye-wood chippers firmly in place, as hereinafter specified.

A is a shaft, which revolves in suitable bearings, and is provided with a fast pulley, B, and a loose pulley, O, to receive the drivingbelt.

To the shaft A is attached awheel,D,in the face of which is formed a \l-shaped groove having slots E formed in its sides and alternating with each other to receive the knives or cutters F.

The slots E may he radial, but I prefer to make them inclined, as shown in Fig. 1, so that the knives F may do their work with a drawing out, and thus work easier.

The knives F are placed in the slotsE, resting-against the shell of the wheel at the rear sides of the slots E and against ribs or projections Gr attached to or formedupon the outer side of the said shell, where the said (No model.)

knives F are secured in place by a cross-bar, .H. The cross-bars H rest against the forward side of the rear part of the knives F, and have inclined lugs I formed upon their ends to rest against the sides of the body and rim of the wheel D, as shown in Figs. 2 and 3, so that the screws passed through the said lugs I and screwed into the wheel D may draw the cross-bars H snugly against the knives F, and thus hold them firmly in place.

The wood to be chipped is laid in a V-shaped feed-trougl'i, J and is designed to be fed forward to the cutting-wheel by a follower operated by a rack and pinion or other suitable feed mechanism. The feed mechanism is not shown in the drawings.

The forward end of the feed-trough J is tapered to correspond with the groove of the cutting-wheel D, so that the wood may be firmly held while being cut. With this construction the dye-woodis cut rapidly into chips of suitable size, to be used for making extract, or to be ground when it is desired to reduce the wood to a powder.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a dye-wood chipper, the combination, with the slotted inclined sides of the \I-shaped face of the cutting-wheel D, of the ribs or projections G and the fastening-bars H, having inclined lugs I upon their ends, substantially as herein shown and described, whereby the knives F will be firmly secured in place, as set forth.

AARON INNIS.
